Earth 2—the alternate reality where all of the animals are evil.
No, Earth 2 is the one where all the animals evolved 20-40 years earlier than on our world. Which makes no real difference in geological time, so you can't actually tell.

And as Marvel fans know, "What If…" is generally followed by lots of death.

I guess that's "open" from the reader's perspective (as opposed to making coded references only), though maybe not the clearest term for it.

As well as the one that never completed filming, Shada.

There are definitely pitfalls to watch out for, but one thing I think is genuinely positive is the increased ease of copying information forward.

Could you make a quick sidetrip to the Library of Alexandria to pick up some Greek plays?

Doctor Who is one of the luckier shows, really, as owing to early fandom every episode survives in audio format. There are other shows we don't even have scripts for.

Mel Blanc scheduled his Yosemite Sam recording last, as well, and didn't perform him in Who Framed Roger Rabbit despite doing all his other old roles.

Doing pretty well for newborn kids, to be fair.

I don't remember that from Amazing Fantasy #15….

Genies aren't all-purpose reality warpers in the 1001 Nights stories, I've noticed. They can do and fetch things very quickly, and do a bit of shape-changing, but that's about it. One if the first stories in some editions is actually a subversion of the whole idea of granting wishes — a genie, on being released, says…

(The Death of Rats holds up a sign reading "Et in Furcadia ego")

The show's kind of reversed Earths 2 and 3 — Earth 2 isn't an outright world-of-evil like the comics' Earth 3, but it does have a lot of flipped good and bad roles. Meanwhile Earth 3 is where the older Flash is from.

I hate to break it to you, but you're probably not going to be able to teach your cats to read.

One answer would be to really emphasise the butterfly effect, with the timeline changes not *quite* putting things back as they were, and the effects rippling out from there.

Ingredients the Okinawans do surprisingly well with….

It's just frustration from having to call all the DC TV series performances 'detectivey'.

You'd make a terrible lifeguard.

So if these four episodes are cut from Imaginary Mary, do they become part of Real Mary?

Yes, but they show that both sides won in different timelines.
